Sian Arnold, Founder and Director

Sian Arnold F.CICB created Insight Bookkeeping & Accounting Services in 2000 to help businesses make better sense of their finances through high-quality bookkeeping services and training. Before moving into the bookkeeping profession, Sian was a small business lending manager with a major High Street bank and so she understands how important it is to have quality, up-to-date financial records if you want your business to grow.  

Sian is a Companion Fellow of the Institute of Certified Bookkeepers (ICB). She is proud of her fellowship status as it signifies the highest grade of ICB membership and in the words of the ICB is ‘reserved for the best of the best’ of the bookkeeping profession who demonstrate they are ‘an outstanding bookkeeper and an exemplary member’. In fact, she was one of the first in the world to be awarded this ICB status. As a fellow, Sian is regularly called upon by the ICB to share her bookkeeping knowledge and experience. Add to this the fact that Insight Bookkeeping & Accounting Services was a nominee for the ICB’s Small Practice of the Year accolade in 2015, then you can see that under Sian’s leadership you are in safe bookkeeping hands.

Away from the daily number-crunching, Sian is dedicated to serving her local community. A former president and also treasurer of the Lions Club of Chipping Norton, she is currently a trustee of her village’s play group. With a passion for the outdoors, Sian helped to run her village’s garden club and has helped to organise garden shows as well as being treasurer of the club. She has been the treasurer of her village’s local allotment group. 

Currently her main focus is as Treasurer and Trustee of the local fund raising charitable association 

Jillian Robinson – Director

Jill joined Insight Bookkeeping & Accounting Services in 2019 and become a director in August 2022.

Jill began her working life in a building society, has worked in pubs & restaurants, had several roles involving stock control and most recently as a ‘checker’ for all customer output in the financial sector.

She has also been a sub-postmistress for the last twenty years alongside running a small retail outlet with her husband.  She is very logical and has always had an interest in numbers along with an almost obsession with grammar and punctuation, which led to her becoming a professional proofreader.

She gained her ICB qualifications through a distance learning course before joining Insight.

Jill is a very ‘indoors’ person and is happiest curled up on the sofa with a good book.

She also enjoys ‘back-to-front’ jigsaw puzzles – where you solve the puzzle without the aid of a picture; general knowledge crossword puzzles and, if she can persuade her sisters, general knowledge quizzes via video calls.
